I have been requested to look at a VB 6.0 extension that is utilizing the
redemption library. It is rather a simple extension that employs a one button
command bar. The button simply adds an html item to the existing html message
in the new message window (HTML only - no word), uses the redemption library
to modify the some properties and a few other things. Essentially the active
code in the extension is ONLY utilized when the user adds this HTML via the
button and will not do anything if the user does not.

So if we create a message without clicking the button to add the HTML and
then send it (no HTML added) we get run-time error on XP SP2 and Vista. My
customer tells me that this just started happening to them after the latest
volley of security patches in the last few weeks.

Symptom #1: On XP we get the following runtime errors

0xD6A4010A AND 0XBFE4010A
"Method '~' of object '~' failed

On Vista we get

0xEB44010A
"Method '~' of object '~' failed

I set break points in the code and message boxes for the release version and
we do not hit any of the code within the extension.

Symptom # 2 - The problem does not happen on development machines (Visual
Studio 2003 & Visual Studio 6.0 installed) we do not get any errors at all.
We have tested this on three development machines. So as far as we can tell
this only happens on machines that are regular users.

Symptom #3 - The problem does not happen when we send an email with the HTML
added. This would mean that the redemption library is actively used and the
button has been depressed meaning the HTML was inserted.

Symptom # 4 - This happens with all versions of the Redemption DLL form 3.4
to 4.3.


Does anyone have any idea what is happening.

Thanks in advance!
